Mandu is a traditional Korean dish consisting of thin wheat flour wrappers filled with meat and vegetables. These dumplings, filled with pork, tofu, glass noodles, and various vegetables, are a beloved Korean soul food enjoyed during holidays, special occasions, and everyday meals. They can be prepared in various ways - steamed, pan-fried, deep-fried, or in soup - making them a family favorite.
Mandu is believed to have been introduced to Korea during the Goryeo Dynasty through Mongolian influence. Initially a food of the royal court and aristocracy, it gradually spread to common people and became established as holiday food and special occasion fare. The ingredients and wrapping methods vary by region and family, each with its own characteristics. Especially during Lunar New Year, tteok-mandu-guk (rice cake dumpling soup) has become a tradition, and in winter, kimchi mandu made with kimjang kimchi is particularly popular. In modern times, with advances in freezing technology, making large batches for frozen storage has become commonplace.
The key to making delicious mandu is controlling moisture in the filling. Tofu must be thoroughly squeezed to maintain a firm, bouncy texture in the filling. Glass noodles should also be completely drained and finely chopped after boiling. Season the filling slightly stronger than usual, as it balances perfectly with the wrapper when eaten together. Don't grind the pork too finely - leaving some texture improves the mouthfeel. When wrapping, press firmly to remove air and prevent bursting during cooking. The more pleats you make, the more attractive the dumpling and the better the chewy texture when cooked.
Making large batches of mandu for frozen storage allows convenient meals anytime. For freezer storage, first freeze dumplings spaced apart on a tray, then once completely frozen, transfer to ziplock bags. This method keeps them fresh for about 3 months. Frozen mandu should be cooked directly without thawing and can be prepared by steaming, pan-frying, deep-frying, or boiling. Steamed mandu are moist and soft, while pan-fried mandu are crispy and savory. Boiled mandu in soup are refreshing, and adding them to tteok-mandu-guk makes a hearty meal. They're even more delicious served with soy-vinegar dipping sauce or seasoned soy sauce.
